Hi Bard,
> I don't find a converter .OBJ --> .JSON; may be you know an utility program that runs, to do that?
For Three.js I found one right on their FAQ page on their wiki:

.JSON is just a way of storing general Javascript data values, so you need not just a .JSON converter but also one that will use the particular formatting of the display engine code that you're trying to use.
